+Under the `related_project_references` you'd find just the original data served by our [JS SDK](https://github.com/Enngage/kentico-cloud-js). Conversely, the `related_project_refereces_nodes` will give you the full-fledged Gatsby GraphQL nodes with all additional properties and links.
+
+Should a *Linked items* element in KC contain items of only *one* type, you'll be able to specify elements and other properties of that type directly (directly under the `related_project_references_nodes` in the above example). However, once you add linked items of multiple types, you'll have to specify their properties using the `... on [type name]` syntax (so called "inline fragments" in the GraphQL terminology).

 #### Content items in Rich text elements relationships
 
 As with the previous example, all rich text properties with inline content items also have an accompanying `_nodes` property.
